Re: Can you put a Nintendo switch psu over RPI400 GPIO?

I just thought of putting a Nintendo switch charger on GPIO of rpi400. Would it create magic smoke efficiently :?: :twisted: I guess the intended switch supply has a type C USB port?! if so, what does the supply state the output voltage is? does it say 5V DC? if not or nothing it mentioned it isn't...

Re: How can I change the GPU memory to more than 128mb on Pi4?

And people are saying, Linux does it for you on the Pi4/400, unless box86 does it differently and needs it allocating*. but then it probably needs allocating within box86 itself. Nothing to do with Steam/GOG/CD.. Hence what it is used for is often needed. *as a side, I would have thought you can set...

Re: Buster ver 10 -- serial port

On the new images did you prepare the serial port (disable console, enable serial). I assume so as you wouldn't have serial on gpio otherwise But check the console part. Also check your working setup in config.sys for disable-bt or miniuart-bt or similar. Did you miss that out if you used it before?...

Re: How can I change the GPU memory to more than 128mb on Pi4?

On the Pi4 the RAM you'll be using should be allocated dynamically. The old config.sys setting if still for the camera memory mainly (and maybe some mpeg decoding?). The new HD camera needed a bit more than 128MB being reserved. It's been a while and not sure what they have changed since the Pi4 fir...

There aren't that many "chips" on the raspberry pi and none of them would be adequately replaced by the RP2040. There are a lot of HATs out there that have microcontrollers on them, the SenseHAT for example, where they could theoretically be replaced by the RP2040. It's a bit larger in si...

Re: How to find Raspberry board type?

If I remember correctly, with recent PiOS, you can just type pinout At a terminal and it gives you the details, mem size, version and a nice picture. Or just to get the version, use raspi-config and it tells you at the top. Of course a picture helps to. :-) Though you seem to have what you need.

Re: RPi 4b Overclock the SD Card?

The over clocking as per Pi3 and before, doesn't work on the Pi4. There has been no mention of any SD card over clocking for the Pi4 The SD card speed is doubled for the Pi4 anyway. It is, but you get similar by doubling the 'speed' on a Pi3 to 100. Iirc the Pi4 still runs at 50, rather than 100. i...
